BACKGROUND OF INVENTION Field of Invention

The present invention relates to improved methods of and systems for controlling water flow, breaking water waves, and reducing surface erosion along river beds, streams, and coastal regions and waterways.

Brief Description of the State of Knowledge in the Art

In general, most armor block shapes have been developed by government agencies to provide solutions for erosion problems and the building of breakwaters for port development.

Since the early 1950's concrete armor shapes have been developed and used throughout the world with varying degrees of success to construct breakwaters around the world. The building of a major breakwater is an extremely costly venture that usually takes years to design and build. When erected in deep water areas, which can generate large waves, the breakwater is generally armored with large concrete armor units because of their superior stability factor over stone when subjected to severe wave attack.

One of the major drawbacks associated with using concrete armor shapes for protection of marine structures is the high cost of producing the units, which are usually cast only once every 24 hours. For a given structure requiring thousands of units, the casting operation can take months and even years to complete a given project. Therefore it is desirable that any shape proposed should preferably be simple to cast at a rapid rate.

Back in the early 1980's, Applicant developed a new and improved concrete armor shape, disclosed in U.S. Pat. No. 4,594,023, for use in the design and construction of breakwaters, flood control structures, armored revetments, jetties and for the rapid building of off-shore islands. In U.S. Pat. No. 4,594,023, Applicant proposed a construction element comprising a trapezoidal inner core supported by trapezoidal legs which space the inner core apart from any surface on which it rests, regardless of which face of the unit is disposed downward. As disclosed in FIGS. 1A, 1B and 1C, the overall shape of this prior art construction element is generally trapezoidal with specifically designed and shaped void segments cut into every plane surface for the release of water pressure to prevent uplift pressures from moving the units out of position. The void segments on each surface of the units also form legs for setting the units and also provides for a void area beneath the blocks for release of hydrostatic head pressure. The leg configuration also permits ease of installation on a rough stone surface. No matter how the units are arranged (patterned or random) the void zones permit escape of water pressure which is of prime importance for stability. When the units are placed pell-mell they form a highly stable mass permitting the release of water pressure in every direction even if one block is placed directly on top of another unit. When the units are set in a pattern, either laying down or standing erect, they form a stable mass, and as wave energy moves up an array of the blocks, it will collide with the water jets that pass through the void areas in each unit.

While the prior art construction unit disclosed in U.S. Pat. No. 4,594,023 offers structural integrity, it has suffered from a number of significant shortcomings and drawbacks. In particular, this prior art breakwater construction block has experienced serious breakage problems when subjected to eccentric movement and consolidation on a breakwater slope. In addition to presenting difficulty during the casting of the units, the four top lugs on the unit experience shearing off or breakage, and have limited the applications for this breakwater construction block design.

Therefore, there is a great need in the art for a new and improved breakwater construction block for constructing seawalls, beach erosion barriers, and systems for controlling and breaking water, and reducing surface erosion along rivers, streams and coastal regions and waterways, and also improved methods and apparatus for manufacturing the same in a flexible and cost-effective manner, while avoiding the shortcomings and drawbacks of prior art systems and methodologies.

DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS OF THE PRESENT INVENTION

Referring to the accompanying Drawings, like structures and elements shown throughout the figures thereof shall be indicated with like reference numerals. As used in this Patent Specification and in the Claims to Invention herein, the term “block” shall include, but is not limited to the terms “unit”, element”, “structure” and “component”, which shall be embraced by the term “block.”

Years of research and experience have been applied to develop the new and improved features of the improved breakwater construction block designs, and interlocking shear key block designs of the present invention, as well as the disclosed methods of and apparatus for manufacturing the same in accordance with the principles of the present invention disclose herein.

Specification of Improved Breakwater Construction Blocks of the Present Invention which can be Manufactured Using a Modular-Type Multi-Form Breakwater Construction Block Molding System

FIG. 6A shows a family of improved breakwater construction blocks of the present invention which can be manufactured using a single modular-type multi-form breakwater construction block molding system of the present invention, illustrated in FIGS. 7 through 9. In a single cross-sectional type schematic, FIG. 6B illustrates the side and cross-sectional dimensions of the family of breakwater construction blocks shown in FIG. 6A. All of these different breakwater construction block designs can be molded, formed or produced from the modular-type multi-form breakwater construction block molding system illustrated in FIGS. 7 through 9, using form attachments, form inserts and filler segments to modify the features of the block designs, and increase the stability factor of the blocks for specific engineering projects. Such modifications to the basic block design produce improved breakwater construction blocks having significantly improved degrees of stability as, for example, the height of the rear leg portions are reduced, as shown by the three lines in FIG. 6B above the right leg of the level unit, so that one can increase the batter and increase the stability of the work constructed from the construction blocks. In many applications, there may be the need to increase the stability of a marine structure by decreasing the surfaces of the breakwater construction block which are influenced by, or otherwise respond to, the hydraulic forces and energy of the water and waves of an ocean, a river or body of water, in the application under consideration. In other applications, there might be a need to slow down the velocity of water to allow suspended sand to collect about the structures to prevent beach and/or coastal erosion as the case may be. Such design tradeoffs and balances will be considered by the design engineer, and further discussed in greater detail hereinafter.

It is an object of the present invention to provide a new and improved modular-type block molding system employing mold inserts, fillers and other devices that enabled the molding of diverse family of breakwater construction blocks having the inventive features shown in FIGS. 6A and 6B, which are required for river and coastal engineering products. As will be described hereinafter, this flexible block molding technology enables engineers to flexibly produce breakwater (i.e. armor) construction blocks having multiple shapes, each with varied void ratios and stability factors, that will satisfy the design criteria for virtually any water and erosion control design problem.

Another object of the present invention is to provide a block molding system that allows the design engineer to easily produce breakwater construction blocks enjoying the many benefits associated with (i) various void zones (e.g. flow through channels), (ii) diverse shape factors, and (iii) proper placement of the construction blocks. When properly designed and placed in strategic locations, void zones formed in breakwater construction blocks provide the design engineer with structures having increased stability, plus being suitable for additional applications. The void zone shapes can be circular, elliptical or conical and will depend on its application. Also the breakwater construction block designs can be made having various depths and heights, the stepped-type breakwater construction blocks can be constructed for slope installations, plus elimination of select void zones, for the fast erection of failed stone structures during severe storms or hurricanes.

By providing large void zones in the stacked breakwater construction blocks, the build up hydrostatic head pressure behind the wall can be greatly reduced, allowing water to flow through and out the resulting constructed work, with the breaking of each ocean wave. Also, and interlocking shear key block designs of the present invention, which function to link neighboring breakwater construction blocks loosely together, can be designed with different heights to close off the space between neighboring breakwater construction blocks of the present invention, as applications may require. At the same time, sufficient flexibility can be provided at the intersection of each interlocking shear key block, so that when struck, hit and hammered by the peaks forces of ocean waves, these constructed works can respond without breakage, yet maintain their structural integrity and continue to perform as intended.

In the case of ocean-groin structures, various permeabilities can be accomplished by providing void zones through the breakwater construction blocks and using the interlocking shear key blocks having multiple heights, installed between the breakwater construction blocks. Improved control of violent wave action can be achieved by off-setting of the breakwater construction blocks in a selected pattern.

Specification of the First Illustrative Embodiment of the Improved Breakwater Construction Block of the Present Invention, and its Use with the Trapezoidal-Type Shear Key Blocks of the Present Invention to Create Diverse Types of Water Permeable and Water-Permeable Marine Structures, for Horizontal, Vertical and Inclined Installation

In FIGS. 7A through 7E, the first illustrative embodiment of the improved breakwater construction block of the present invention 1A is shown comprising: a central trapezoidal core portion 2 of substantially trapezoidal cross-sectional dimensions; a set of four trapezoidal support legs 3A through 3D, each extending from one corner of the central trapezoidal core portion in a radially-extending manner; a bottom portion 6 of substantially planar dimensions, raised off a support surface 8 by a distance d determined by the distance that the leg portions 3A through 3D extend beyond the bottom planar surface 6 of the core portion 2; and a tower-type portion 4 (e.g. at least ½ the height of the central trapezoidal core portion) extending axially along the central axis 5 of the central trapezoidal core portion 2, and having a planar top surface 7. The purpose of the tower-type portion 4 is to break up and slow down the flow of water passing over the central trapezoidal core portion 2, and allow sand suspended in water to settle within the breakwater construction work erected on the beachfront, oceanfront or coastal waterway.

The rugged breakwater construction blocks of the present invention shown in FIG. 6A have been designed for building water impermeable and water-permeable marine structures, alike, such as sea walls, bulkheads, and impermeable ocean-groins, as required by the application at hand. In order to construct these marine structures, the present invention also employs trapezoidal-like interlocking shear key blocks 10A, shown in FIGS. 28A through 29B, that fit precisely between the interstices 11 formed between neighboring breakwater construction blocks 1A and 1A, as shown in FIGS. 30A through 30D, to create a structural interface and seal 12 between each breakwater construction block/interlocking shear key block arrangement formed thereby.

FIG. 30A shows an exemplary section of a marine construction (e.g. seawall, oceanwall, riverwall, erosion-protection structure) employing the tower-type type breakwater construction block 1A shown in FIGS. 8A through 8E and the interlocking shear key block design 10A′ which is a slight modification from the designs shown in FIGS. 28A and 28B, where the breakwater construction blocks are spaced closely together and the length of the interlocking shear key block is equal to the total length of the central core portion and its tower portion, to form a tight fluid seal. As shown in FIG. 30A, interlocking shear key design 10A has substantially planar side surfaces, whereas side surfaces in the interlocking shear key block designs shown n FIGS. 28A through 28B have notches or grooves extending along the length of each side surface.

FIG. 30B shows an exemplary section of a marine construction employing the tower-type type breakwater construction block 1A shown in FIGS. 8A through 8E and the interlocking shear key block design 10A′ shown in FIG. 30A, where the breakwater construction blocks are spaced apart and the length of the interlocking shear key block is equal to about half of the total length of the central core portion and its tower portion.

FIG. 30C shows an exemplary section of a marine construction employing the flat-top type breakwater construction block 1D shown in FIGS. 12A through 12E and the interlocking shear key block design 10A′ shown in FIG. 30A, where the breakwater construction blocks are spaced apart and the length of the interlocking shear key block is equal to about half of the total length of the central core portion and its tower portion.

FIG. 30D shows an exemplary section of a marine construction employing the low-profile breakwater construction block 1H shown in FIGS. 16A through 16D and the interlocking shear key block design 10A′ shown in FIG. 30A, where the breakwater construction blocks are spaced apart and the length of the interlocking shear key block is nearly twice the total height of the breakwater construction block 1H.

These block assemblies can be used to construct water, sand, and/or soil impermeable sea walls, erosion-protection systems, and other kinds of marine-engineering works, as required in many civil-marine engineering applications. Hereinafter, numerous examples and illustrations will be provided on how this novel marine engineering technology can be applied to solve diverse engineering problems.

Attention is now turned to the basic improved breakwater construction block designs, and improved methods for manufacturing the same, along with the interlocking shear key blocks that interconnect the breakwater construction blocks, in accordance with the principles of the present invention. In general, the breakwater construction block design 1A shown in FIGS. 7A through 7E has a total height to widest base dimension (H/W) ratio of approximately H/W=5/3, which can be scaled to any practical size, as required by the construction application at hand.

Also, preferably, a notch 9 is formed in the outer surface of the middle of each leg portion 3A through 3B, to allow each block to be banded together with other blocks while assembled as a subsystem 30, as shown in FIGS. 51 through 53. Breakwater construction block design 1A can be further modified to include additional features that will provide added functionality and performance to the constructed block, selected on the end-user application, for example: (i) pass-through channels (e.g. void zones) 11 as shown in FIGS. 18A through 18E that allow water to flow therethrough with minimal hydraulic resistance, and thus providing more stability in ocean-groin type constructions, in particular; (ii) recessed surface voids 15 formed on the outside rear surface of the central portion of the breakwater construction blocks 1B, as shown in FIGS. 39 and 39A, to allow crushed rock in a rock shelf to integrate with an assembly of breakwater construction blocks of the present invention; (iii) truncated rear leg portions 16, and also optionally truncated portions of the lower rear portion of the central core portion 2, as shown in FIGS. 10B1 through 10B4, and 14A through 14E, and illustrated by the dotted lines indicated in FIG. 6B, to increase the batter of wall structures constructed using such modified breakwater construction blocks 1B, 1F, and interlocking shear key blocks used to build such works of civil engineering and design, as illustrated in FIGS. 39A, 41A, 42B; (iv) modified height, surface geometry and/or features of the top (i.e. tower) portion 4, as shown in FIGS. 11A through 11E, 12A through 12E, 14A through 14E, 15A through 15D, and 19A through 19E; (v) modified height of the central core portion and top portion of the breakwater construction block, as shown in FIGS. 16A through 16D; and (vi) modified specific density of the central core portion 3, by molding voids 17 therein during a first stage of manufacture, and then filling in the voided region with a higher density concrete material 18 during a subsequent manufacturing stage, as shown in FIGS. 20A through 20D, and 21A through 21C and 21D and 22E; (vii) modified central core portion 3 by molding an axially void 19 is formed therein during block manufacture, so that a pile or like structure can be passed through the breakwater construction block 1I as shown in FIGS. 17A through 17E, and into the earth for increased stability; and (viii) modified central core portion 3 to include a mounting post or attachment 20. These modifications to the basic “reference” breakwater construction block 1A shown in FIGS. 7A through 7E, provide added features identified above, and specified in Block Reference Model of FIG. 6B, which will be described in greater detail hereinafter.

Transportable ISO-Shipping Container Block Factory System for Manufacturing the Family of Breakwater Construction Blocks and Interlocking Shear Key Blocks of the Present Invention, at any Construction Site Around the World

As shown in FIGS. 8A through 10A, an object of the present invention is to provide a transportable breakwater construction block factory system 35, contained within an ISO-shipping container 36, stored at a warehouse 38, for dispatch and shipment (e.g. via rail, air, roadway or sea) to a remote work site location 40, near an oceanfront, for in situ manufacturing of breakwater construction blocks 1A through 1M, and interlocking shear pin key blocks 10A, 10B of the present invention. In the illustrative embodiment of FIGS. 8C through 8D, the ISO-shipping container 36 is transported by a tractor-trailer combination comprising a tractor 37A pulling a trailer 37B, carrying ISO-shipping container 36.

As shown in FIGS. 8A through 8E, the breakwater construction block manufacturing system 39 comprises: the ISO-shipping container 36 containing a plurality of multi-form block molding subsystems 41 for simultaneously molding break water construction blocks 10A through 10M, and block molding subsystems 42 for interlocking shear key blocks 10A, 10B, wherein each subsystem has a base mold portion 41A, 42A that is mechanically coupled to the factory floor 38, and a side molding portion 41B, 42B being mechanically coupled with a movable framework 43, operated manually or using hydraulics, so that all or multiple groups of side mold portions (for the construction blocks and the matching key blocks) can be simultaneously lift (e.g. by a hydraulic crane on site) and remove the side mold portions from molded concrete blocks; top mold portions 41C; and fillers, attachments, etc 44 for modifying the breakwater construction block and shear key block molds to realize the required design features in the concrete blocks to be manufactured. The actual number of multi-form block molding subsystems 41, 42 actually installed on the transportable factory platform 38, and contained within the ISO-shipping container 36, will depend on several factors including the H/W ratio of the breakwater construction block design, the number of interlocking shear key block designs supported by the system, the length of the interlocking shear key blocks, etc.

As shown in FIG. 8E, the transportable block manufacturing system 39 is designed for use with locally-supplied hydraulically-powered cranes 45, concrete mixers 46, tractors 47, and other equipment (e.g. generators, jack hammers, rock drills, GPS tracking equipment, i etc) 48 arranged about the breakwater construction block factory platform 38 temporarily set up at a construction work site 40 where the breakwater construction blocks and interlocking shear key blocks of the present invention are to be efficiently manufactured using the multi-form block molding technology of the present invention. When the concrete has set (e.g. typically within 5-6 hours), these formed blocks can be removed from their molds, brought to a holding zone for a curing time of several days, and then transported to GPS-specified locations on the construction work site. At the work site, the formed blocks can be assembled together, to construct the any system design under construction with an unprecedented level of efficiency, flexibility and economy.

For breakwater construction blocks having a total block height of 5 feet and base dimensions of 3+ feet, it will be possible to install at least 20 (2×10) breakwater construction block molding subsystems 41, 42 on the factory platform 38 slidably received with an 8×8×40 ISO-shipping container having a length of 40 feet, a width of 8 feet and a height of 8 feet. Alternatively, at least 10 breakwater construction block molding subsystems 41, and at least 10 interlocking shear key block molding subsystems 42, can be mounted on the factory platform 38 that slides within a 8×8×40 ISO-shipping container. In some arrangements, it may be desirable to mount only breakwater construction block molding subsystems 41 on the factory platform 38 of a first ISO-shipping container, and mount all interlocking shear key block molding subsystems 42 on a separate factory platform in another ISO shipping container. This way, multiple ISO-shipping containers will be sent to the construction site to build a portable block molding system of the present invention.

In some applications of the present invention, multiple ISO-shipping container block factories will be required to meet the block manufacturing demands of any given construction project, anywhere around the world. Each ISO-shipping container can contain block molding subsystems on the factory platform designed to produce blocks required by the project design. As ISO shipping containers have size restrictions determined by the standards, it is understood that each molding subsystem can be dismantled into its basic components during shipping/transport, in applications where the height of the breakwater construction blocks exceeds the 8-9 foot height limitations, and the base width of the blocks exceeds the 8 foot limitations of most ISO-shipping containers.

Specification of the Multi-Form Block Molding Subsystem Configured for Different Breakwater Construction Block of the Present Invention

FIGS. 9A1 and 9A3 shows a breakwater construction molding subsystem of the present invention 41, mounted on the factory platform 38, configured together and ready for concrete to be poured into the mold, through the top pour opening, to form a tower-type breakwater construction block 1A as shown as No. 1 in FIG. 6A.

FIGS. 9B1 through 9B3 show the steps that are performed after a block is molded. In FIG. 9B1, the top mold portion 41C is removed from the side mold portion 41B, and then in FIG. 9B2, the side mold portion 41B is slidably-lifted off the formed block. The final step involves lifting the molded block off the base portion 41A.

FIG. 9C1 shows a breakwater construction molding subsystem of the present invention 41, mounted on the factory platform 38, configured together and ready for concrete to be poured into the mold, and form a concrete breakwater construction block 1D shown in FIGS. 12A through 12E and identified by Block “#11” (i.e. flat top design) in FIG. 6A. After concrete is poured through the top opening of the side mold portion 41B, the side mold portion 41B is slid off the cured block, and thereafter, the block 1D is lifted off the mold base portion 41 by a crane, lift or other suitable device.

FIGS. 9D1 through 9D8 shows the breakwater construction molding subsystem configured for a tower-type breakwater construction block 1J with flow through channel 14, as shown in FIGS. 18A through 18E and identified by Block #2 in FIG. 6A (tower-type with side flow channel). The water flow channel (i.e. a positive void-ratio) 14 allows free flow passage of water through the structure, and lowers the resistance of the block to hydraulic flow. This flow channel decreases the weight of the block but increases the porosity (i.e. flow characteristics) thereof. This block design can be used to construct a permeable ocean-type groin, generally-erected perpendicular to the ocean shoreline, as shown in FIGS. 36A through 36F.

As shown in FIGS. 9D1 through 9D8, these pass-through channels (i.e. void zones) 14 can be formed using a pair of paraboloid-type channel molding sections 41D1 and 41D2 (e.g. formed from metal, plastic and/or foam) that are joined in the midsection of the side mold portion 41B. As shown in FIGS. 9D1 and 9D2, each flow channel molding section 41D1, 41D2 has an integrated handle portion 41E for pulling the molding section out of a molded concrete block 1D, and also a pair of spring-loaded releasable locking mechanisms 41F1 and 41F2 (about the outer side of the molding section) which releasably locks with the aperture 41B1, 41B2 formed in the side molding section 41B to which the channel molding section 41D1, 41D2 attaches, during mold configuration and concrete pouring operations. After the side molding portion 41B has been attached to the mold base portion 41A, then the flow channel molding portions 41D1 and 41D2 are slid through apertures 41B1 and 41B2 in the side mold portion 41B and slidably joined together in the middle of the side mold section 41B. Spring-loaded releasable locking mechanisms 41F1 and 41F2 in the flow channel mold portions 41D1 and 41D2 engage with the top and bottom portions of the apertures 41B1 and 41B2, respectively, on opposite sides of the side mold section 41B, and hold the joined together flow channel mold portions 41D1 and 41D2 together in place during concrete pouting and curing operations. Thereafter, the top mold portion 41C is attached to the side mold portion 41B.

After concrete has been poured into the configured mold, through the top opening of top mold section 41C, and it has sufficiently cured, then the top molding portion 41C is ready to be slid over and off from the top portion of the concrete block 1D. Then the side mold portion is ready to be slid off the concrete block 1D, But first, the releasable lock mechanisms 41F1 and 41F2 must be released from the outer apertures 41B1 and 41B2 formed in the flow channel molding sections 41D1 and 41D2, respectively. These flow channel mold sections 41D1 and 41D2 will remain in the molded concrete block after the side mold section 41B is slid off the molded concrete block. To remove these channel mold sections 41D1 and 41D2 from the molded concrete block, the user manually pulls the integrated handle 41E in the outside of each channel mold section, and then pulls the channel mold section out from the molded channel 14 within the concrete block 1D. Preferably, the channel mold sections 41D1 and 41D2 will be made from a material which is non-porous and slippery to concrete once cured so that the cured concrete material does not bond to the channel mold sections. Lubricants can be added to the outer surface of the channel mold sections to facilitate the release of the channel mold sections from the molded concrete block, as is well known in the concrete block manufacture art.

While formation of paraboloid channels 14 in breakwater construction blocks 1D has been discussed above, it is understood that such void zones 14 can be made with circular, elliptical or conical cross-sections through the overall breakwater construction block. When void zones 14 are properly designed and placed in strategic locations in the central core portion 2 of the breakwater construction block, the design engineer can build blocks that demonstrate increased stability in diverse applications in the field of civil and marine engineering. Such void zones and flow through channels increase the porosity of the breakwater construction blocks and this generally guarantees a higher stability factor when the blocks are subjected to wave action.

Alternatively, void zones can be formed half-way, quarter-way or three-quarters-way through the breakwater construction blocks. In such designs, where the void zones do not pass completely through the central core portion of the block, the central core portion 2 of the block can be provided with integrated heat exchange coils, to facilitate the exchange of thermal energy between water within the voids, and heat exchange fluid passing through the heat exchange coils.

Specification of Molding Operations for the Trapezoidal Interlocking Shear Key Blocks of the Present Invention

FIG. 9E shows a trapezoidal interlocking shear key block molding subsystem 41 in greater detail. While this molding subsystem is designed for molding the trapezoidal interlocking shear key block 10A shown in FIGS. 28A and 28B, it can be readily adapted to mold the interlocking shear key block 10B shown in FIGS. 29A and 29B, and other variations of such shear key blocks.

In general, the trapezoidal shear key block molding subsystem 41 comprises: a base mold portion 41A for molding the surface features of the bottom of each interlocking shear key block 10A 10B; and a side molding portion 42B for molding the trapezoidal surface features of each trapezoidal interlocking shear key block 10A, 10B. The mold sections 42 a and 42B can be made from metal, plastic and/or any other suitable material that is strong and durable enough to allow the mold/form withstand the pressure generated from poured concrete before and while it is cured.

Preferably, each interlocking shear key (i.e. wedge) block 10A (10A′) includes an integrally formed hook 10A1 (e.g. made from steel or other metal) that is inserted into the top core portion of the shear key block before concrete into the top opening of the mold has had an opportunity to cure. Interlocking shear key (i.e. wedge) block 10B (10B′) includes an integrally formed hook 10B1. Once cured, the hook portion 10A1 is securely connected to the core portion 10A2 of the interlocking shear key block 10A, and can support the full weight thereof during lifting, transport and placement operations during construction work. During construction work, the hook 10A1 (10B1) will be used to pickup and place these shear key blocks 10A, (10A′), 10B, (10B′) into trapezoidal interstices 11 formed between neighboring breakwater construction blocks 1H.

This truncated block design is shown in FIGS. 10B1 through 10B4 and 14A through 14E, and provides new shape for the speedy erection of revetments, and other marine structures, can be erected on incline surfaces of up to 60 or so degrees with excellent performance results.

The shape factor of the battered breakwater construction block 1B in FIGS. 10B1 through 10B4 is achieved by removing the tower top mold/form portion 41C, and inserting a sloped filler section 41G at the bottom of the base mold portion 41A, conform to slope angle requirements for a specific project, as illustrated in FIG. 10A. The sloped filler section 41G also truncates leg portions 3A′ and 3D′, and also removes a portion of the bottom of the central core portion 2 of the breakwater construction block 1B. Depending on the application and engineering requirements, the slope of the filler section 41G could be as large as 60 or so degrees, to allow the resulting breakwater construction block 1G to be erected or mounted on an inclined surface of 60 or so degrees, so that the central axis 5 of the block is normal to the Earth's surface (i.e. gravitational forces) and the top surface 7B of the block is parallel with the level of the sea.

As shown in FIGS. 10B1 through 10B4, the second improved breakwater construction block of the present invention 1B comprises: a central trapezoidal core portion 2 of substantially trapezoidal cross-sectional dimensions; a set of four trapezoidal support legs 3A′ through 3D′, each extending from one corner of the central trapezoidal core portion 2 in a radially-extending manner; and a pair of the trapezoidal support legs 3A′ and 3D′ being truncated at its bottom end; and a tower-type portion 4 (e.g. at least ½ the height of the central trapezoidal core portion) extending axially from the central trapezoidal core portion 2 for breaking up and slowing down the flow of water passing over the central trapezoidal core portion of the breakwater construction block. This breakwater construction block design can be used in combination with any of the interlocking shear key blocks of the present invention illustrated in FIGS. 28A through 29B and FIG. 30A.

The interlocking is achieved by installing (e.g. lowering onto place) interlocking shear key block 10A between each neighboring pair of tower-type breakwater construction blocks 1B to form an impermeable seawall revetment structure 100, constructed with great economy.

This breakwater construction block design can be used in combination with any of the interlocking shear key blocks 10A illustrated in FIGS. 28A through 29B. To mold the mini-tower top portion of the breakwater construction block 1C, a different top mold portion 41C′ would be used that conforms to the geometry of the mini-tower top portion 4C of the block 1C.

The shape factor of the battered breakwater construction block 1F in FIGS. 14A through 14E is achieved by removing the tower top mold/form portion 41C, and inserting a sloped filler section 41G at the bottom of the base mold portion 41A, conform to slope angle requirements for a specific project, as illustrated in FIG. 10A. The sloped filler section 41G also truncates leg portions 3A′ and 3D′, and also removes a portion of the bottom of the central core portion 2 of the breakwater construction block 1F. Depending on the application and engineering requirements, the slope of the filler section 41G could be as large as 60 or so degrees, to allow the resulting breakwater construction block 1F to be erected or mounted on an inclined surface of 60 or so degrees, so that the central axis 5 of the block is normal to the Earth's surface (i.e. gravitational forces) and the top surface 7F of the block is parallel with the level of the sea.

This breakwater construction block design can be used in combination with any of the interlocking shear key blocks of the present invention illustrated in FIGS. 28A through 29B and FIG. 30A.

After concrete has been poured into the assembled molding system, through the top opening of the side mold portion 41B, the axially-disposed shaft 20 is inserted into the concrete. A shaft holding/alignment bracket (not shown) that straddles across the top of the side mold portion 41D is used to hold the shaft 20 axially in place, until the concrete cures, and then it can be removed.

This breakwater construction block design can be used alone or in combination with any of the interlocking shear key blocks of the present invention illustrated in FIGS. 28A through 29B and FIG. 30A.

The breakwater construction block 1J has a reduced void ratio when compared to a similar installations with void regions. The selection of the varied units will depend on wave energy at the site, material in suspension, littoral drift at a specific location, construction equipment available, method of placement, and outcome desired by the design engineer. This breakwater construction block 1J can be also utilized to protect from washout, roadway embankments along coastal highways.

Specification of the Breakwater Construction Block of the Eleventh Illustrative Embodiment of the Present Invention

FIGS. 19A through 19E show an eleventh illustrative embodiment of the construction block of the present invention 1K comprising: a central trapezoidal core portion 2 of substantially trapezoidal cross-sectional dimensions; a set of four trapezoidal support legs 3A through 3D, each extending from one corner of the central trapezoidal core portion 2 in a radially-extending manner; a medium-height tower portion 4K (e.g. at least ¼ of the central trapezoidal core portion) extending axially from the central trapezoidal core portion 2 for slowing down the flow of water over the central trapezoidal core portion of the breakwater construction block. This breakwater construction block design can be used in combination with any of the interlocking shear key blocks of the present invention illustrated in FIGS. 28A through 29B and FIG. 30.

Specification of the Breakwater Construction Block of the Twelfth Illustrative Embodiment of the Present Invention, Having Different Specific-Density Concrete Regions

Exceptional benefits are derived by increasing the specific gravity, and thus the armor protection/stability capacity, of the breakwater construction blocks of the present invention. As an example, in order to obtain equal protection from stone having a specific gravity of 2.3, as compared to a specific gravity of 2.7, it would be necessary to increase the weight of stone 100% and increase the thickness of protection 25%. To achieve such specific density requirements in a breakwater construction block, different specific density concrete regions are provided in the improved breakwater construction block shown in FIGS. 20A and 20B, using the molding technology and techniques illustrated in FIGS. 21A through 22E.

FIGS. 20A and 20B show a breakwater construction block 1L having multiple specific density concrete characteristics, comprising: a central trapezoidal core portion 2 of substantially trapezoidal cross-sectional dimensions having a first concrete region 2A with a first specific density, and a second concrete region 2B having a second specific density which is greater than the first specific density; a set of four trapezoidal support leg portions 3A through 3D (each having notched region on the outer surface for banding operations); wherein each leg portion extends from one corner of the central trapezoidal core portion in a radially-extending manner; and a tower-type portion 4 (i.e. at least ½ of the central trapezoidal core portion) extending axially from the central trapezoidal core portion 2 for slowing down the flow of water over the central trapezoidal core portion of the breakwater construction block. This breakwater construction block design can be used in combination with any of the trapezoidal interlocking shear key blocks 10A, 10A′ and 10B illustrated in FIGS. 28A through 29B and FIG. 30A.

Specification of the Method of Molding Breakwater Construction Blocks Having Different Specific Density Regions

FIGS. 21A through 22E shows a method of molding a breakwater construction block design, having multiple regions of different specific densities. In the illustrative embodiment, this is achieved by creating a void zone 17 along the central axis of each breakwater construction block using tapered form insert 41J, as shown in FIGS. 21A, 21B and 21C. After the concrete has set or cured (e.g. after five-six hours), the top mold portion 41C is first removed from the molded concrete block, and then side mold portion 41B is removed from the molded concrete block. Then, the tapered form insert 41J within the molded concrete block, shown in FIGS. 22A through 22D, is removed as shown in FIG. 22E, to create a void zone along the central axis of the central core portion of the block. The central void zone 17 is then filled with heavy weight (e.g. high specific gravity) concrete to produce the breakwater construction block shown in FIGS. 20A and 20B. This illustration provides a simple method to increase specific gravity of any breakwater construction block design, and will provide a beneficial effect on the stability of such breakwater (armor) construction blocks of the present invention.

FIGS. 25A through 25C shows a breakwater construction block system 140 configured for protection against erosion along beaches, streambeds and riverbeds, and constructed using a third arrangement of the breakwater construction blocks shown in FIGS. 11A through 11F.

FIGS. 26A through 26C shows a breakwater construction block system 150 configured for protection against erosion along beaches, streambeds and riverbeds, and constructed using a fourth arrangement of the breakwater construction blocks shown in FIGS. 11A through 11F.

Specification of the Interlocking Shear Key Block for Interconnecting the Breakwater Construction Blocks of the Present Invention

To construct water impermeable dams and seawalls, Applicant has developed interlocking shear key blocks 10A and 10B shown in FIGS. 22A through 22B for use with all of the different breakwater construction block designs of the present invention. As will be described in great detail hereinbelow, these interlocking shear key blocks 10A, 10A′, 10B, 10B′ can be made to having different lengths and widths provided they have trapezoidal surface characteristics that are designed to match up with the trapezoidal surface characteristics of the breakwater construction blocks under various block placement conditions involving the inter-spacing of the breakwater construction blocks. These interlocking shear key blocks, having integrated pick-up hooks 10A1, 10B1, can be picked up, transported and lowered into place between the breakwater construction blocks, to build overall structures that resolve many pressing engineering problems facing our world, in a simple and cost effective manner.

FIGS. 28A and 28B show a first illustrative embodiment of an interlocking shear key block for use in connection with the breakwater construction blocks of the present invention, wherein the X and Y cross-sectional dimensions of the interlocking shear key block are substantially equal. FIG. 30A shows a modification of the design illustrated in FIGS. 28A through 28B. FIGS. 29A and 29B show a second illustrative embodiment of an interlocking shear key block for use in connection with the breakwater construction blocks of the present invention, wherein the X and Y cross-sectional dimensions of the interlocking shear key block are substantially un-equal. In other alternative embodiments the X, Y characteristics may be substantially equal at certain cross-sections of the shear key block, and substantially un-equal at other cross-sections thereof. Notably, the trapezoidal surfaces of the shear key block and its corresponding trapezoidal surfaces on the breakwater construction block are important by virtue of the fact that it is the mated planar surfaces of the blocks that achieves the interlocking action described above.

The interlocking shear key blocks play an important role in the design of the various marine structures that can be erected with the breakwater construction block system of the present invention. As shown, the interlocking shear key blocks 10A, 10B can be reduced in height for specific engineering applications, such as a release zone in a dam structure during flood stage. Interlocking shear key blocks 10A, 10B can be produced with various degrees of permeability to suit design criteria, or can be made impermeable. In a single line of units, the shear key only locks the blocks together, so they are resistant to movement from horizontally-directed forces as well as uplifting (vertically-directed) forces. The manner in which the interlocking is achieved is as follows. An interlocking shear key block does not lock a zone of neighboring breakwater blocks together unless forced are exerted on the breakwater blocks to lift them up, roll them over, or tilt them in some way, in which case, the interlocking shear key blocks generate sufficient shear forces to locking the breakwater construction blocks together at the interlocking shear key block zone, to prevent failure of the system when the blocks are properly sized. It is understood that the spacing of the breakwater construction blocks, and height of the shear key blocks will depend on the application. Many different sizes and configurations are illustrated in FIGS. 30A, 30B, 30C and 30D, and described below.

FIG. 30A shows a series of tower-type breakwater construction blocks shown in FIGS. 7A through 7E, assembled together along a single tier, in a side by side relationship, and interconnected by an interlocking shear key block design 10A′ slightly modified from the design shown in FIGS. 28A and 28B, and inserted between each adjacent breakwater construction blocks, to create an semi-permeable barrier to water and soil flow.

As shown, the bottom edges of the leg portions on one side of each breakwater construction block is aligned close to against the bottom edges of the leg portions of one side of a neighboring breakwater construction block, and the interconnecting shear key block is inserted between each such neighboring block to form a tight water seal. In this embodiment, the length of each interlocking shear key block is substantially equal to the length of the central portion of the neighboring mini-tower breakwater construction blocks. Also, each breakwater construction block has a short tower portion for slowing down the flow of water passing thereacross. As can be seen from FIG. 31B, this earth-surface erosion protection barrier system offers great protection from the scouring or erosion of the earth surface (e.g. ocean bottom, stream bottom, river bottom) due to the flow and impact of water.

FIGS. 32A through 32C show a breakwater construction block system 180 for protection against erosion along beaches, streambeds and riverbeds, and constructed using a second arrangement of the mini-tower breakwater construction blocks 1C shown in FIGS. 11A through 11F. As shown, the bottom edges of the leg portions on one side of each breakwater construction block 1C is aligned in a spaced apart relationship to against the bottom edges of the leg portions of one side of a neighboring breakwater construction block 1C, and the interconnecting shear key block 10B of the type shown in FIGS. 29A and 29B is inserted between each such neighboring block 1C to form a tight water seal. In this embodiment, the length of each interlocking shear key block 10B is substantially equal to the length of the central portion of the neighboring mini-tower breakwater construction blocks. Also, the interlocking shear key block is disposed between the sidewall surfaces of adjacent break water construction blocks, so that longer dimension of adjacent interlocking shear key blocks 10B are aligned in orthogonal cross-sectional directions within the breakwater construction block system. Also, each breakwater construction block 1C has a short tower portion for slowing down the flow of water passing thereacross. As can be seen from FIG. 32B, this earth-surface erosion protection barrier system offers great protection from the scouring or erosion of the earth surface (e.g. ocean bottom, stream bottom, river bottom) due to the flow and impact of water. Also, this structure enables the collection of sand on ocean-fronts to control beach erosion.

FIGS. 33A through 33C show a breakwater construction block system 190 for protection against erosion along beaches, streambeds and riverbeds, and constructed using a third arrangement of the mini-tower breakwater construction blocks shown in FIGS. 11A through 11F, aligned along their leg portions, rather than their sides, as shown in FIGS. 31A through 32C. As shown in FIGS. 33A through 33C, an interlocking shear key block 10B of the type shown in FIGS. 29A and 29B is disposed between the sidewall surfaces of a first set of opposing break water construction blocks 1C and also between the leg portions of a second set of opposing breakwater construction blocks, so that the longer dimension of each interlocking shear key block 10B extends between the side wall surface of the first set of opposing breakwater construction blocks, whereas the shorter dimension of each interlocking shear key block extends between the leg portions of the second set of opposing breakwater construction blocks. As shown, each breakwater construction block 1C has a short tower portion for slowing down the flow of water passing thereacross. As can be seen from FIG. 33B, this earth-surface erosion protection barrier system offers great protection from the scouring or erosion of the earth surface (e.g. ocean bottom, stream bottom, river bottom) due to the flow and impact of water.

Specification of Erosion-Prevention Systems Installed at the Bottom of Riverbeds and Streambeds

FIGS. 34A and 34B show a riverbed erosion-prevention system 200 installed at the bottom of a riverbed, constructed as an arrangement of breakwater construction blocks connected together by interlocking shear key blocks 10A, 10B, as shown in FIG. 31A, 32A or 33A. When installed, water is allowed to flow over the installed riverbed erosion-prevention system, while preventing erosion and/or scouring of the riverbed (i.e. bottom surface) and thus uphold the sidewalls of the river. Such systems will be placed at strategic locations where the flow of water has a tendency to scour and erode the river bottom, and maintenance of the river sidewalls is of critical importance.

FIGS. 35A and 35B shows a streambed erosion-prevention system 205 installed at the bottom of a streambed, constructed as an arrangement of breakwater construction blocks connected together by interlocking shear key blocks, as shown in FIG. 31A, 32A or 33A. When installed, water is allowed to flow over the installed streambed erosion-prevention system, while preventing erosion and/or scouring of the streambed (i.e. bottom surface) and thus uphold the sidewalls of the stream. Such systems will be placed at strategic locations where the flow of water has a tendency to scour and erode the stream bottom, and maintenance of the stream sidewalls is of critical importance.

Specification of a Groin-Type Beach Erosion-Prevention Barrier System Constructed from Multiple Tiers of Breakwater Construction Blocks and Interlocking Shear Key Blocks of the Present Invention

FIGS. 36A through 36F show a groin-type beach erosion-prevention barrier system 210 that has been constructed from multiple tiers of mini-tower breakwater construction blocks shown in FIGS. 18A through 18E having flow through water channels 217, and interlocking shear key blocks shown in FIGS. 28A and 28B which are used to interconnect the breakwater blocks along a given row 211, 212, 213, 214 in the groin-type system 210. As shown in FIGS. 36A and 36E, each breakwater construction block in the system has a pass through water flow channel 14 (i.e. a positive void ratio) passing through one side of the block to the other side, that allows water passage through the structure when erected in the permeable groin-type system. In general, the groin-type system 210 will be erected perpendicular to the shoreline, but this may vary from application to application.

Conventional ocean-type groins have usually been built with stone and have allowed no or little permeability, causing severe erosion down drift of such structures. Unlike the conventional ocean-groin systems, the ocean-groin of the present invention 210 permits sand and water to pass through the structure, thereby allowing material held in suspension to pass through the structure and assisting a more nature method in maintaining an even beach profile on each side of the structure. While passing through the ocean-groin work of the present invention, water energy is dissipated, water velocity is slowed down, and the large amounts of sand suspended in the ocean water are allowed to deposit on both sides of the work, thereby preserving the beach front on the oceanfront.

FIGS. 36A through 36C show the groin-type beach erosion-prevention barrier system 210 as employing an arrangement of four tiered rows 211, 212, 213 and 214 of interconnected breakwater construction blocks 1J shown in FIGS. 18A through 18E, assembled symmetrically about of linear mound of 216 on a beach shore as shown in FIG. 36F. The mound of sand must be protected from washout by installing filter-fabric over the sand mound in a conventional manner. As shown, each row of breakwater construction blocks 211, 212, 213, 214 is constructed by a series of breakwater construction blocks 1J shown in FIGS. 18A through 18E connected together by interlocking shear key blocks 10A shown in FIGS. 28A and 28B. As shown, these interlocking shear key blocks 10A have a height less than the central trapezoidal core portion of the breakwater construction blocks, to facilitate the reduction of water speed across the breakwater construction blocks and cause sand to collect and settle around and on both sides of groin structure as water flows through the flow through channels in each breakwater construction block, thereby preventing beach erosion.

Alternatively, this single-tier system 230 can be constructed by placing breakwater construction blocks 1A at 8 feet apart from each other, measured from the center of each block, attaching timber or like sheeting to the rear of the blocks, then nailing filter-fabric to the sheeting, and then backfilling the wall structure with sand or crushed stone.

The increased stability of the overall work is achieved by the wedging and interlocking of stones and/or crushed gravel into recessed voids formed in the concrete breakwater construction block becomes an integral part of the overall structure.

Method of Constructing Erosion-Protection Systems Using Preassembled Subsystems, Banding Techniques and Interlocking Shear Key Blocks of the Present Invention

Many different marine engineering systems have been disclosed in great technical detail. Some of these system will be constructed above land, some under the ocean waters, and some along the beach or oceanfront or at a waterway-land interface. In nearly all instances, construction of marine systems underwater always presents challenges when assembling components requiring alignment, underwater cameras, etc well known in the art. To lessen the technical challenges associated with underwater construction, and construction along any land-water interface, it is another object of the present invention to provide an improved method of constructing erosion-protection systems using preassembled subsystems, banding techniques, and interlocking shear key blocks.

According to this improved method of construction, the breakwater construction block are pre-assembled together on land into subsystems, then interlocked using interlocking shear key blocks, banded together, and then transported to the designated construction site location for installation in the work under construction, using a crane system or the like. These method steps are repeated as many times as required to build resultant system designs, underwater, above land, and/or along the coast line, with greater efficiency and safety. The details of this method will now be described in detail below.

As indicated at Step A in FIG. 51, the first step in the method of constructing erosion-protection systems involves forming breakwater construction blocks with notches on the outer surface of the leg portions (i.e. which can be achieved by forming notches in the block molds).

As indicated at Step B in FIG. 51, the second step in the method involves assembling multiple breakwater construction blocks 1A through 1L on land, and using interlocking shear key blocks 10A, 10A′, and/or 10B, 10B′ to interlock the blocks to form a subsystem 30.

As indicated at Step C in FIG. 51, the third step in the method involves banding together the assembly of breakwater construction blocks 30 using a banding structure 400 under tension. The banding structure 400 can be a steel band, a wire cable or other harnessing structure with sufficient flexibility. Notably, each block will be provided with notches 9 which the banding structure 400 can reliably grip.

As indicated at Step D in FIG. 51, the fourth step in the method involves transporting the assembly 30 to site where the system is to be constructed, as illustrated in FIG. 52. A crane or lift 500 with suitable cables 410 can be used for such lifting and transporting operations shown in FIG. 52.

As indicated at Step E in FIG. 51, the fifth step in the method involves removing bands 400 from the preassembled subsystem 30 of breakwater construction blocks.

As indicated at Step F in FIG. 51, the sixth step in the method involves repeating Steps A through E above, at least one or more times, so as to place multiple assemblies 30 in their designated locations at the work site to form a resultant system 450 which is created by interconnecting these subsystems 30 using interlocking shear key blocks 10A, 10B, as illustrated in FIG. 53.

Using the method illustrated in FIGS. 51 through 53, civil and marine engineers can now more easily and economically construct marine structures that are submerged underwater, or partially underwater because the greater part of subassembly can take place on dry land. The interconnection of preassembled subsystems is achieved by lowering interlocking shear key blocks 10A, 10B and/or 10A′, 10B′ into place between neighboring breakwater construction blocks 1A and 1L using a crane or winch system 500, well known in the art. The banding apparatus 400 used to band together the preassembled blocks on land, can be made from steel, fiberglass or any other material that is flexible and has sufficient strength to support the load of the block subassembly during lifting, transport and placement operations during construction work at the site. While the notches formed in the leg portions of the blocks is a preferred method of gripping and grapping each block in an subassembly of interlocked blocks, alternative methods of banding may be used including passing cable through preformed holes in the blocks for the specific purpose of subassembly, or otherwise provided and available for block banding purposes.

Modifications that Come to Mind:

The breakwater construction blocks of the present invention are provided with a rugged top portion that can have several design shapes as shown in the drawings, and when combined with other construction blocks and interlocking shear key blocks disclosed herein, will serve an important function, namely total water energy control and its reaction to wave attack, changing flow velocities through a composite structure which can allow sand, shell or stone particles in suspension more time to settle. In order to control severe problems along our shorelines including rivers, streams and bluffs, improved breakwater construction block should be ideal block for rapid construction of off-shore berms which are effective in controlling shoreline erosion.

The present invention provides a new system for molding the various block designs of the present invention using attachments that provide engineering solutions never before available from a single-type molding system. As an example, a breakwater construction unit that provides a superior foundation block for all classes of highway and railroad signals, marine-type projects as well as foundation pads for wind power installations. The breakwater construction block of the present invention provides a significantly higher stability factor against over-turning, or pullout, when compared against the cylinder and upright rectangular blocks now in conventional use. During severe hurricane winds and heavy rain, numerous pole failures have occurred which can be eliminated using the construction block system of the present invention. The basic shape factor of the improved construction block provides the highest degree of soil-friction against overturning and pullout, and provides a structural element that becomes attached to a large soil-mass, which resists removal by natural forces.

The wall systems described above can also be used to control snow avalanches by building walls using breakwater construction blocks and interlocking shear key blocks as taught herein. Such avalanche control structures can replace conventional stones used throughout Europe for such kinds of engineering.

It is understood, that numerous other modifications will readily occur to those with ordinary skill in the art having had the benefit of reading the present disclosure.
